The saturated vapour pressure of antimony and its sulphide and oxide at different temperatures are shown in Fig. 2.As can be seen from Fig. 2, as the temperature increases, the saturated vapour pressure of Sb 2 S 3, Sb 2 O 3 and Sb increases gradually, and the growth trend of Sb 2 S 3 is the most rapid. When the temperature is below 1201 …

Antimony exists in four main oxidation states: –3, 0, +3, and +5. The most common in environmental, biological, and geochemical systems are Sb(III) (the trivalent form) and Sb(V) (the pentavalent form). In nature, antimony trioxide (Sb2O 3) exists in minerals such as valen-tinite and senarmontite (Roper et al. 2012, ATSDR 2019).

Antimony is also used for pigments in plastics, paints, rubber, and for a wide variety of minor uses, including medicines, fireworks and others. ... Antimony oxide is a brilliant yellow color, accounting for much of the …

Most supply was coming from the Chinese stibnite mines (mainly the Xikuangshan mine), stibnite is the most common antimony ore mineral, ... In Fig. 1 this process is illustrated by feedback loop B5. ... No public data was found on global antimony oxide production per country or facility. This study includes the production of the largest …

Preparation of Antimony Sulfide and Enrichment of Gold by Sulfuration–Volatilization from Electrodeposited Antimony. Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the….

A description of each of these as well as oxide reduction follows (Motoo, 1974, Vladislav, 1981, Yong-Fu and Wei-Tao, 1981). Oxide volatilization: Removal of antimony as the volatilized trioxide is the only pyrometallurgical method suitable for low grade ores. Combustion of the sulfide components of the ore supplies some of the heat; …
